3D histograms?

Are there any packages, commands, etc, that include ways to create 3D
hisograms? My hope is for something like my colleagues can easily
make in something like Excell, i.e., a an display with rectangular
columns with the heights analogous to heights in a regular 2d
histogram.
Thanks!
